Abstract

Dengue is an emerging disease, and the distribution of the mosquito vector is partially mediated by environmental conditions. In this article, a new conceptual model is suggested that emphasizes the importance of including environmental variability in mosquito modeling studies. In an applied sense, mosquito habitat maps are developed for Hawaii using a GIS overlay of mosquito survival thresholds of temperature, precipitation, and stream/wetland location. Populated areas represent locations with the potential for an outbreak. The maps are adjustable based on expert knowledge input, and efforts to prevent or control outbreaks can be concentrated in those zones delineated by this study.
